Cydia

It was mentioned earlier today that Apple will be rolling out iOS 5 for anyone with a supported iPhone, iPad, or iPod Touch on October 12th. The iOS 5 Gold Master is already available to Apple Developer accounts though and furthermore, developers can also jailbreak it.

The iPhone Dev Team hasn’t yet released an official update to the RedSn0w jailbreak utility to support the latest release yet but MuscleNerd previously confirmed that you can use the recently updated RedSN0w 0.9.9b2 for Mac or Windows to jailbreak iOS 5 Gold Master. You will need to specificy the IPSW you want to chose and you should point it towards the iOS 5 beta 7 IPSW for now – until the new version of RedSn0w is out.

Remember that this is a tethered jailbreak, which means if you reboot your iPhone, iPod Touch, or iPad – you’ll need to connect to a computer via a USB cable and run Redsn0w again OR lose your jailbreak.

You can follow our step by step guide on how to jailbreak iOS 5 GM using RedSn0w 0.9.9b2 below, but first you will need to make sure you have the following things:

After selecting the iOS 5 beta 7 IPSW, you should see the following screen:

Step 4: Go back to the main menu for RedSn0w and now hit Jailbreak, make sure Install Cydia is checked off, then hit Next (see screenshots below):

Step 5: You will be asked to make sure your device is turned off and plugged in, please make sure this is the case then proceed by clicking Next. RedSn0w at this point will give you instructions to follow to successfully enter your device in DFU mode (see screenshots below):

At this point your device should have scrolling white text initially and afterwards you should see the familiar RedSn0w pineapple logo with the current state of your iOS device. Just be patient and shortly after your device will successfully be jailbroken.

Step 6: Before you proceed, if you check your Cydia icon, you will see there is a blank icon for it. You need to successfully boot one last time. To do this, go back to the main menu on RedSn0w while keeping your iOS device plugged in and hit Extras, then click Just Boot. Follow the instructions to enter DFU mode one last time and it will successfully boot.

Voila! You are done! You have just successfully jailbroken your iOS device on iOS 5 GM.

Update

Redsn0w 0.9.9b3 was released (updated on our previous post as well). It now auto-detects the IPSW - no longer do you need to point at the beta 7 IPSW. So you can follow the same procedures with the exception of having to point toward the iOS 5 beta 7 IPSW repeatedly. Download links for the updated version can be found below:

help!! I have been trying to upgrade from 4.3.3 to ios 5 . iTunes is being stupid and giving me error 1600. I am using a macbook pro and the latest version of itunes. I have tried everything. TinyUmbrella, redsnow, and dfu mode, but nothing seems to work. If someone could help me with this it would really make my day

I would love to try this but I've been reading that syncing, both wired and wireless, isn't working between iOS 5 devices and PPC Macs. Has anyone else run into this issue? iTunes beta says it supports PPC but I just want to be sure.

Ps: yes, I know that redsn0w is Intel only. I can use a friend's Intel machine for the actual JB but I have an old G5 that I just want to sync with.
